Schneider Electric MPPT 80
34 fault codes documented
Capacitor Over Temperature — The Capacitors are too hot
The internal capacitors have become too hot, potentially affecting performance and longevity. The system may shut down or derate.
Battery Over Temperature Shutdown — The battery is too hot
The battery temperature is too high, causing the system to shut down to prevent damage. Charging will resume once the battery has cooled down sufficiently.
Ambient Over Temperature — The Ambient temperature is too high
The surrounding temperature is too high for the device to operate safely. The device may reduce its output power (derate) or shut down to prevent damage.
Output Under-voltage Immediate — The DC Output Voltage is too low
The DC output voltage has dropped too low, immediately triggering a fault. This indicates a potentially serious issue with the output or power source.
Output Under-voltage — The DC Output Voltage is too low
The DC output voltage is lower than the expected or required level. This could impact the performance of connected devices.
Auxiliary Power Supply Fault — The Auxiliary Power Supply has shut down
The Auxiliary Power Supply has shut down, indicating a fault. This may require manual clearing.
Battery Under Temperature Shutdown — The battery is too cold
The battery temperature is too low for safe charging, causing the system to shut down. Charging will resume automatically when the battery temperature rises to an acceptable level.
Auxiliary Power Supply Fault — The Auxiliary Power Supply has shut down
The Auxiliary Power Supply has shut down, indicating a fault. This may require manual clearing.
Heatsink Over Temperature Shutdown — The heatsink is too hot
The heatsink has become too hot, causing the device to shut down to prevent internal damage. This is often due to high ambient temperatures or blocked ventilation.
Ground Fault — A ground fault has occurred
A ground fault has been detected in the system. This is a safety issue and requires attention. This fault requires manual clearing.
Configuration Fault — An incorrect configuration setting is preventing the system from running
An incorrect setting in the device's configuration is preventing it from operating correctly. This may require a restart after checking settings.
DC Over-voltage shutdown — The Auxiliary Power Supply has shut down
The Auxiliary Power Supply has shut down due to an over-voltage condition. This means the voltage it's receiving is too high, potentially causing damage. This fault may require manual clearing.
DC Over-current shutdown — DC output current is too high
The DC output current is exceeding the safe limit, causing the device to shut down to prevent damage. This may require manual clearing.
SPS Overload — Overload on the Secondary Power Supply
The Secondary Power Supply (SPS) is experiencing an overload, meaning it's trying to deliver more power than it's designed for. This can cause the supply to shut down.
Slow Output Over Current Error — Output Current is too high
The output current is exceeding the safe limit, but the device is designed to manage this with a slower response. This can still lead to overheating or damage.
Input Over Voltage Fault — The DC Input voltage is too high
The DC input voltage is too high, triggering a fault. This condition requires attention to prevent damage to the device. This fault may require manual clearing.
Fan Over Voltage Fault — The Fan voltage is too high
The voltage supplied to the cooling fan is too high, which could damage the fan motor. This fault typically does not disable normal operation.
Fan Over Current Error — The Fan current is too high
The current being drawn by the cooling fan is too high. This could indicate a fan motor issue or a short circuit.
Input Over Current Error — DC Input current is too high
The current coming from the DC input is too high for the device to handle safely. This can lead to component damage if not addressed.
Output Over Current Fault — The DC Output current is too high
The DC output current exceeds the safe operating limit, causing a fault. This can prevent charging and may require manual clearing.
Fan Over Current Fault — The Fan Current is too high
The current drawn by the cooling fan is too high, indicating a potential issue with the fan motor or wiring. This fault may require manual clearing.
Fan Under Voltage Fault — The Fan voltage is too low
The voltage supplied to the cooling fan is too low, which may prevent it from operating effectively or at all. This fault typically does not disable normal operation.
Fan Under Current Fault — The Fan current is too low
The current drawn by the cooling fan is too low, which could indicate a problem with the fan motor or its connection. This fault typically does not disable normal operation.
Network Power Supply Fault — The Network Power Supply has failed
The power supply responsible for network communication has failed. This will prevent the device from communicating on the network.
External BMS Disconnected — Communication lost with Battery Management System
Communication has been interrupted between the charge controller and the battery's management system. This prevents proper battery monitoring and charging control.
Battery equalization did not occur — Controller must complete a bulk/absorption cycle first
The battery equalization cycle has not started even though it was enabled. The charge controller requires completion of a bulk or absorption charging phase before equalization can begin.
DC Input Over Voltage Warning — The DC Input Voltage (PV) is too high
The DC input voltage from the PV panels is higher than recommended but not yet critically high. This is a warning that may lead to a fault if conditions persist.
DC Over-voltage shutdown — Input voltage is too high
The DC input voltage is too high, causing the system to shut down. This can occur if the DC input voltage exceeds the operating specifications.
Error/Warning (red) LED on or flashing — Active fault, error, or warning is present
The red LED is illuminated or flashing, indicating that an active fault, error, or warning is present on the charge controller. The specific issue can be determined via the InsightLocal interface.
InsightLocal indicates an input over voltage error — PV panels are producing voltage levels outside operating specifications
InsightLocal is reporting an input over-voltage error. This typically occurs when the voltage from the PV panels is too high for the charge controller, often due to cold weather.
On/Charging (green) LED flashing — Charge controller is outputting charge current
The green LED is flashing, indicating that the charge controller is actively sending current to charge the batteries. This is a normal operational status.
Red LED flashing — Warning condition present
The charge controller's red LED flashes when there is a warning. A warning message will also be displayed on the gateway device. Normal operation continues until the warning escalates to a fault.
Red LED solid — Fault or error condition present
The charge controller's red LED is solid when a fault or error is present. A fault message will also be displayed on the gateway device. MPPT and charging functions may be disabled.
Thermal derating is indicated in InsightLocal — Controller is operating in high temperature with high power
InsightLocal shows that the charge controller is operating at reduced power due to high ambient temperatures and high power output. This is a protective measure.
